In the MTU Size field, enter a value from 616 to 1500.
The default size is 1500 bytes.
6. Click the Apply button.
Your settings are saved.
If you suspect an MTU problem, a common solution is to change the MTU to 1400. If
you are willing to experiment, you can gradually reduce the MTU from the maximum
value of 1500 until the problem goes away. The following table describes common MTU
sizes and applications.
Table 1. Common MTU sizes
ApplicationMTU
The largest Ethernet packet size. This setting is typical for connections that do not use
PPPoE or VPN and is the default value for NETGEAR routers, adapters, and switches.
1500
Used in PPPoE environments.1492
Maximum size to use for pinging. (Larger packets are fragmented.)1472
Used in some DHCP environments.1468
Used in PPTP environments or with VPN.1436
Set Up and Manage Dynamic DNS
Internet service providers (ISPs) assign IP addresses to identify each Internet account.
Most ISPs use dynamically assigned IP addresses. This means that the IP address can
change at any time. You can use the IP address to access your network remotely, but
most people do not know what their IP address is or when this address changes.
To make it easier to connect when you use OpenVPN, you can get a free account with
a Dynamic DNS service that lets you use a domain name to access your home network.
To use this account, you must set up the router to use Dynamic DNS. Then the router
notifies the Dynamic DNS service provider whenever its IP address changes. When you
access your Dynamic DNS account, the service finds the current IP address of your home
network and automatically connects you.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic
DNS service does not work because private addresses are not routed on the Internet.
